- Define boot log related HSP message ID's.
- Call camrtc_hsp_vm_read_boot_log as the first step during the HSP
handshake.
- The read_boot_log function will wait for 2000 ms for a boot log
message. If the RCE has hung during boot, this will timeout, and return
with error.
- Move dev_set_drvdata to before camrtc_hsp_probe in camrtc_hsp_create.
Explanation: The RCE, during a normal boot sequence, will boot before
the RTCPU KMD starts probing, so the mailbox will already be full
when the HSP driver is initializing. The RTCPU HSP full interrupt
handler will be called immediately after the handlers are registered
by the mailbox driver. The interrupt handler will reference the HSP
device's drvdata, and it was a race condition as to whether the
interrupt handler would be called before the drvdata was set.
Thus, this change sets drvdata before the interrupt handlers are
installed to prevent this race condition.
- Update the full interrupt handler to return if camhsp is null.

Create and register set and get operating point sysfs functions.
The operating point notification will contain the requested
operating point.
The nvcap resource manager will extract the operating point
from the notfication and send it to rce via the hsp command
interface.
In turn, rce will apply the operating point by adjusting the
functional clock frequencies for the following camera ip:
- rce hardware
- vi hardware
- isp hardware
- nvcsi
